The technical problems of low service life and difficult maintenance of the bearing are solved.
In order to achieve the above object, the technical solution of the present invention is an integral sealed double-row tapered roller bearing, which includes a first inner ring, a second inner ring, a double-raceway outer ring, a first tapered rolling element, a second tapered rolling element, a first sealing assembly, and a second sealing assembly; the rolling bearing is characterized in that a retainer is arranged between the first inner ring and the double-raceway outer ring, a first conical rolling body is arranged on the retainer, a retainer is arranged between the second inner ring and the double-raceway outer ring, a second conical rolling body is arranged on the retainer, a first sealing assembly is arranged between the first inner ring outside the first conical rolling body and the double-raceway outer ring, and a second sealing assembly is arranged between the second inner ring outside the second conical rolling body and the double-raceway outer ring.
Further, the first sealing assembly comprises an L-shaped sealing part, a special-shaped sealing ring and a U-shaped sealing part; the double-raceway outer ring is connected with an L-shaped sealing part, the L-shaped sealing part is connected to a U-shaped sealing part tightly attached to the first inner ring through a special-shaped sealing ring, and the L-shaped sealing part, the special-shaped sealing ring and the U-shaped sealing part completely seal the first conical rolling body on the inner side of the first sealing assembly.
Based on the technical scheme, the bearing sealing device adopts a composite integral sealing device combining micro-contact and labyrinth seal.
Furthermore, a protrusion is arranged on the side face of one end of the L-shaped sealing part, and the protrusion is matched with an indent arranged on the outer ring of the double-roller way.
Further, the second sealing assembly is structurally symmetrical to the first sealing assembly.
Furthermore, the bearing also comprises a front cover, a rear stop and a plastic steel connecting ring; the end part of the first inner ring is provided with a front cover, the end part of the second inner ring is provided with a rear gear, and the second inner ring is connected with the rear gear through a plastic steel connecting ring.
Based on the technical scheme, the novel plastic-steel-mounting connecting ring is adopted, and the anti-creeping technology is adopted.
Furthermore, a bolt is installed on the front cover, and an anti-loosening sheet is arranged between the bolt and the front cover.
To explain the utility model further, the bearing comprises a double-raceway outer ring, two inner rings, a retainer, a conical rolling element, a seal assembly, a front cover, a rear baffle, a plastic steel connecting ring, a bolt and an anti-loosening sheet. The bearing ring material adopts G20CrNi2MoA (electro slag remelting) steel, so the steel material can ensure that the bearing has good impact resistance during the operation process. The compact integral sealed double-row tapered roller bearing is adopted to reduce the axial installation space of the bearing, improve the bearing space of the torpedo car and adapt to the heavy-load transportation requirement.
The bearing for the original torpedo car is an open bearing, namely, a sealing device is not arranged, the traditional contact type seal and labyrinth seal form a sealing system of the bearing with a sealing seat, the novel torpedo car adopts a heavy-load compact structural design, and the sealing seat is cancelled for the compact bearing seal, so that the sealing system is required to be independently formed and matched with an inner ring and an outer ring to form a unitized bearing. The bearing sealing device adopts a composite integral sealing device combining micro-contact and labyrinth seal.
The bearing unit, the front cover and the rear baffle form an integral installation space after the bearing is installed, and are fastened after the bearing is installed by bolts. The bearing inner ring and the rear block are connected by the plastic steel connecting ring, so that abrasion particles can be effectively prevented from entering the matching surface of the bearing, and meanwhile, the rear block is connected with the bearing, and the installation of a user is facilitated.
The compact integral type sealed double-row tapered roller structure bearing is used in a torpedo tank car bearing for the first time; the bearing sealing device adopts a composite integral sealing device combining micro-contact and labyrinth seal; a novel plastic-filled steel connecting ring is adopted, and an anti-creep technology is adopted.
The utility model has the advantages that: the maintenance-free period of the integral sealed double-row tapered roller bearing is 8 years, and lubricating grease is not required to be supplemented in the maintenance-free period.
